Mental Math Apps?

All of the threads I've seen on WSO are from 10+ years ago so I figured I would start another one.


Currently prepping for interviews and want to make sure that my basic mental math is good enough for giving approximate answers. Two digit multiplication, division, that type of stuff. Has anyone found any such apps that test your mental math skills and aren't marketed towards 5 year olds?

 

I used to practice with digital clocks as a kid. Let’s say it’s 3:07 at the time I’m commenting this. Do 3x7, 7/3, etc. All permutations. Then you can use military time, 15:07. 15 * 7, 7/15, 15/7. (15 *3) / 7. Just keep doing that all the time.
